I'll check it out, thanks!

EDIT: After a quick look, I like what I see in general. The biggest suggestion that I would make and the part of SendWithUs that really appealed to me was the recipient focus of the interface.

Being able to look to a specific user, see what had been sent to them, delivery status, resend it if necessary, etc. That was a very appealing and useful way to deal with the email logs from my perspective.
